Manufacturing Quality Control of H-D-PRO-OTBU
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 205 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | Chiral HPLC | Enantiomeric excess measured using a chiral stationary phase and UV detection, resolving D- and L-proline-OTBU peaks. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to quantify water via stoichiometric reaction. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common solvents (e.g., THF, EtOAc, hexane). |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion and plasma ionization. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Content | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Mass loss after high-temperature ashing; residue weight reflects inorganic impurities. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral identity and enantiomeric consistency. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change, used for identity and purity screening. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity under controlled lighting against defined standards. |
| pH of Aqueous Solution | pH Meter | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension or solution. |
